Filed: 1996-02-19
Granted: 2001-01-02
Abstract: In a speech coding system which encodes speech parameters into a plurality of frames, each frame having a predetermined number of bits, a predefined numberof bits per frame are employed to transmit a speech parameter delta. The speech parameter delta specifies the amount by which the value of a given parameter haschanged from a previous frame to the present frame. According to a preferred embodiment disclosed herein, a speech parameter delta representing change in pitch delay from the present frame to the immediately preceding frame is transmitted in the present frame, and the predefined number of bits is in the approximate range of four to six. The speech parameter delta is used to update amemory table in the speech coding system when a frame erasure occurs.

Title: Expanding dental implant and method of use
Inventor: HANOSH FREDERICK N
IPC: A61C8/00
Filed: 1995-05-10
Granted: 2005-11-15
Abstract: The technical field of the invention generally concerns an expandable dental implant for receiving and supporting a dental prosthesis. The expandable dental implant, securable within a bore formed into bone of a patient's jaw, includes an elongated, hollow, tubular barrel having both an attachment end and an insertion end. The barrel has both a threaded interior surface for screwing the implant into the bore, and a threaded exterior surface for receiving a threaded expander screw. The barrel is pierced about its insertion end by a plurality of radial slits spaced circumferentially around the barrel. The interior surface of the barrel at the insertion end is formed wi th a smaller diameter than the diameter of the interior surface of the barrel a t the attachment end. The expander screw and the interior surface of the barrel ar e shaped so advancement of the expander screw along the barrel toward the insertion end causes an end surface of the expander screw to collide with th e interior surface of the barrel, and to expand the insertion end outward into the surrounding bone.

Abstract: A ventilation system having a hood located above cooking equipment which generates heat and fumes due to cooking. The hood has an inclined air filter at the back of the hood which rests on a flange extending along the length of the hood at the top thereof and the bottom of the inclined air filter rests on a grease collector extending along the length of the hood. The grease collector is located at a given distance downwardly from the top of the hood. The back of the inclined air filter defines an exhaust area, and the hood also includes an exhaust duct being in direct communication with the exhaust area and a fan for drawing the contaminated air out of the exhaust area. The hood also has a fresh air output that is connected to a fresh air duct including a fan and located along the length of the hood at the front thereof, this fresh air output being designed to inject fresh air into the hood. The invention is characterized in that the fresh air output of the hood is positioned to direct fresh air towards the inclined air filter at an upwards angle with respect to horizontal. The system further has a fresh air diffuser located behind the cooking equipment and near the floor, connected to the fresh air duct and being devised to diffuse air upwardly and downwardly. In use, the fresh air output forces the contaminated air to exit through the filter as it directs a steady stream of fresh air towards the filter. The fresh air diffuser feeds fresh air downwardly, which increases the burner efficiency of the cooking equipment and upwardly at the back of the cooking equipment, which creates air movement towards the hood reducing the amount of stale air that is present near the floor and behind the cooking equipment.

Granted: 2005-01-18
Abstract: In an electric power steering device comprising a yoke made of a tubular member and carrying permanent magnets, and a hollow motor shaft coaxially and rotatably received in the yoke to carry a motor armature which cooperates with the permanent magnets to form an electric motor for the power steering device, a section of the yoke extending from an axial end thereof to a part thereof surrounding an axial end of the motor shaft defines an inner diameter which is greater than an outer diameter of the nut member so that the output torque of the electric motor can be measured during the course of assembling the power steering device by allowing a testing tool to be inserted from the open end of the yoke without any interference and to be applied to an suitable part of the nut member or the motor shaft. Thus, the performance of the electric motor can be directly evaluated before the power steering device is fully assembled so that any faulty electric motor can be either rejected or repaired before any further assembling work is conducted.
